Answer:
B
Step-by-step explanation:
The number 
is 8 times greater than 
thus, 
multiply both sides by 
we get 
if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8
then B is the answer
Answer:
$455
Step-by-step explanation:
The computation of the principal is shown below:
As we know that
Amount = Simple interest + Principal
Let us assume the principal be X
So,
Amount = $500
Simple interest = Principal × rate of interest × time period
= X × 5% × 2 years
= X × 0.1
So, the principal is
$500 = X × 0.1 + X
$500 = 1.1 × X
So, the X is $455 i.e principal
